CornerRounding

public class CornerRounding internal constructor(
    internal val value: Float,
    internal val unit: Int,
    internal val smoothing: Float,
)

Defines the radius and smoothness of rounding at a polygon vertex.

• Unrounded (radius = 0) keeps a sharp corner.
• smoothing = 0f rounds the corner with a circular arc.

the adjacent edges (1f maximizes the flanking curves).

• smoothing > 0f extends symmetric cubic Bézier flanking curves from the circular arc toward

Create instances with CornerRounding.dp, CornerRounding.fraction, or Unrounded.

Properties

Unrounded

public val Unrounded: CornerRounding = CornerRounding(0f, UnitDp, 0f)

Sharp corner with a rounding radius of zero.

Functions

dp

public fun dp(
            radius: Dp,
            @FloatRange(from = 0.0, to = 1.0) smoothing: Float = 0f,
        ): CornerRounding

Creates a CornerRounding with a radius in Dp.

Parameters

Throws: IllegalArgumentException

if radius is negative/unspecified or smoothing is outside 0f..1f

fraction

public fun fraction(
            @FloatRange(from = 0.0, to = 1.0) fraction: Float,
            @FloatRange(from = 0.0, to = 1.0) smoothing: Float = 0f,
        ): CornerRounding

Creates a CornerRounding with a radius as a fraction of the polygon's size.

For polygons defined with a radius (such as PolygonShape.regularPolygon, PolygonShape.star, and PolygonShapeScope.polygon with radius), the corner radius is `fraction * radius. For polygons defined with custom vertices ([PolygonShapeGeometry](/jetpack-compose/androidx.compose.foundation/foundation/classes/PolygonShapeGeometry/api)), which do not have a radius, the corner radius is a fraction of the polygon's smaller dimension (min(width, height)`).

Parameters

Throws: IllegalArgumentException

if fraction or smoothing is outside 0f..1f
